Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590802, here are decompositions:

11 + 31590791 = 31590802
71 + 31590731 = 31590802
251 + 31590551 = 31590802
359 + 31590443 = 31590802
389 + 31590413 = 31590802
401 + 31590401 = 31590802
431 + 31590371 = 31590802
449 + 31590353 = 31590802

Showing the first eight; more decompositions exist.
